Google+ lets people make their profile be private. If a user decides to keep their profile private, then the language "hasn't filled out their profile" is what shows up.

A spokesperson tells us, "The beauty of Google+ profiles is that people can choose to share information - such as their employment or education - with select circles, rather than publicly. This is intentional and gives Google+ users greater control over the content people can see about them."

Google adds, "The current text when people visit a profile that they don't have access to view reads: XX has not filled out her/his profile yet."
